* scmsigs.h, async.h: updated.
* _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL loop. * posix.c (scm_uname): interpret only negative values as an error. Solaris normally returns a positive value. * script.c (scm_compile_shell_switches): if we are not going into an interactive repl, set scm_mask_ints to zero so that asyncs can run. * simpos.c (scm_system): don't ignore/unignore signals around the "system" call. * posix.c (scm_open_pipe): don't ignore/unignore signals around the "popen" call. * init.c (scm_boot_guile_1): don't call scm_init_signals, it's done in boot-9.scm instead. * scmsigs.c, async.c: Major rewriting of signal handling code. (scm_sigaction): new procedure. (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the timing. (scm_raise): return unspecified, throw error on failure. * boot-9.scm: signal-handler, alarm-thunk: removed. don't define ticks-interrupt etc. top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS during call to scm-style-repl. * acconfig.h: mention HAVE_RESTARTS. * configure.in: check for sigaction and restartable system calls.
